The fsVarsBVarGet function can be used to get the value of a specific BVar.

 

Syntax
FsVarError fsVarsBVarGet(
    FsBVarId bVarId,
    FsUnitId unitId,
    double* result,
    FsObjectId target
);

 

Parameters
ParametersDescription
bVarId

The ID of a BVar (found using fsVarsGetBVarId).

unitIdThe ID of a unit (found using fsVarsGetUnitId).
resultThe variable that will receive the value of the BVar if others parameters are correct.
target

The ID of the object from which the variable is being retrieved.

 

Return Values

The function returns a FsVarError, where 0 means there is no error (in which case, the value of the BVar has been set in result).

 

Example
FsUnitId unitId = fsVarsGetUnitId("BOOLEAN");
FsAVarId bVarId = fsVarsGetBVarId("AUXILIARY_SUNSHADE_ADJUST_PILOT", false);
double result = 0;
if (fsVarsBVarGet(bVarId, unitId, &result, FS_OBJECT_ID_USER_AIRCRAFT) == FS_VAR_ERROR_NONE)
{
    // valid
}
else
{
    // error
}
